According to Au7o's research across NHTSA recalls, manufacturer TSBs, and owner forum reports, the 1991 Toyota Corolla has 2 documented known issues, with 1 rated critical. The most serious is Head gasket failure at high mileage causing coolant loss and oil contamination ($800-$2,500 repair). Across all issues with published estimates, repair costs range from $300 to $2,500. DIY maintenance guides at au7o.io.
On the 1990-1997 Toyota Corolla, on high-mileage 4A-FE/7A-FE engines the head gasket is one of the most frequently reported major failures, usually precipitated by a prior overheat event (often from a neglected cooling system, failing radiator, or stuck thermostat) rather than a design defect. Failure lets coolant migrate into the cylinders or oil galleries. Owners report gradual unexplained coolant loss with no external puddle, white/gray exhaust steam, and milky oil on the dipstick and filler cap. Because the aluminum head warps when overheated, a proper repair includes checking the head for flatness.
Coolant level dropping with no visible external leak
White or gray steam from the exhaust
Milky/brown sludge on oil cap and dipstick
Overheating or temperature gauge climbing
Bubbles in the coolant reservoir
Rough running or misfire from a coolant-fouled cylinder
How to Fix
Confirm with a cooling-system pressure test, combustion-gas (block) test at the coolant, and compression check. Replace the head gasket; have the cylinder head checked for flatness and resurfaced if warped, and replace the timing belt, thermostat, and any degraded coolant hoses while access is open. Address the original overheating cause (radiator, water pump, thermostat, fan) to prevent recurrence.

On the 1990-1997 Toyota Corolla, the 4A-FE and 7A-FE are belt-driven and require timing belt replacement on a mileage/age interval (Toyota's ~60,000-mile figure, considered conservative by many owners). A benefit of this engine family is that it is a non-interference (free-running) design, so a snapped belt leaves you stranded but does not bend valves or destroy the engine. On decades-old cars the rubber belt and the front cam/crank seals are wear items regardless of mileage; a seized or leaking water pump or a failed tensioner/idler can lead to overheating and, in turn, the head-gasket failures noted above. Note the 4A-FE water pump is reachable without removing the timing belt, so it is replaced on condition (weeping weep-hole) rather than always as a set.
Common Symptoms
Coolant leak or weep from the water pump area
Whining or rattle from the front of the engine
Engine suddenly dies and cranks but won't start (snapped belt)
Overheating from a seized water pump
Squealing or chirping from the timing cover
How to Fix
Replace the timing belt on schedule and inspect/replace the tensioner, idler, and the front crank/cam seals while the cover is off since the labor overlaps. Replace the water pump if it shows any weep or bearing play, and refresh coolant and the thermostat. If a belt has already snapped, because the engine is non-interference you can simply re-belt and inspect rather than face valve damage.
